本発明は、走行中の車両の軸重を測定して該車両の重量
を測定する方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for measuring the weight of a moving vehicle by measuring the axle load of the vehicle.
走行中の車両は、各稲はね系により振動し重心の移動が
生じるため、その軸重は、静止時の軸重を中心として変
動する。従来の軸重測定は、軸重測定用の検出板(下膜
に、複数の荷重変換器の上に載荷板が配設されている)
が小さいため、上記変動する軸重値の一時の値しか計測
できず、従って測定結果が不正確となる欠点があった。A running vehicle vibrates due to each spring system and shifts its center of gravity, so its axle load fluctuates around the axle load when it is stationary. Conventional axle load measurement uses a detection plate for axle load measurement (a loading plate is placed on the lower membrane on top of multiple load transducers).
Since the value is small, only a temporary value of the fluctuating axle load value can be measured, which has the disadvantage that the measurement results are inaccurate.
この軸重値の変動を減少させるためには検出板自体は勿
論のこと、その検出板前後のある長さの路面を厳密に平
坦に仕上げる必要がある。しかしながら、この平坦仕上
げは、技術的にかなり困難であり、経済的にも著しく不
利を伴なう。In order to reduce this variation in the axle load value, it is necessary to make not only the detection plate itself but also a certain length of the road surface in front of and behind the detection plate strictly flat. However, this flat finishing is technically quite difficult and economically disadvantageous.
ところで、軸重を測定し、車両総重量を測定するには、
1台の車両の各軸の軸重値を総計することとなるが、そ
の場合、同一車両の軸重か他の車両の軸重かを判別する
必要がある。この判別方法としては、目視により行なう
方法と目視によらず、光電管、ループコイル、速度計等
の機器を組み合わせて自動的に判別する方法とがある。By the way, to measure the axle load and total vehicle weight,
The axle load values of each axle of one vehicle are totaled, but in this case, it is necessary to determine whether the axle load is of the same vehicle or another vehicle. This discrimination method includes a visual method and an automatic discrimination method using a combination of devices such as phototubes, loop coils, speedometers, etc. without visual inspection.
この後者の従来の車両判別装置は、光電管、ループコイ
ル、速度計等の単機能検出器からの検出情報を適宜電気
的に処理して車種を判別するものであるため、装置が複
雑化するという難点があり、また必らずしも正確な車種
判別を行ない得るものではなかった。The latter type of conventional vehicle identification device is said to be complicated because it electrically processes detection information from single-function detectors such as phototubes, loop coils, and speedometers to determine the vehicle type. This method has its drawbacks, and it is not always possible to accurately identify the vehicle type.
本発明は、上記事情に鑑みなされたもので、その目的と
するところは、測定用桁上面およびその前後の路面を平

方法を提供することにある。The present invention was made in view of the above circumstances, and its purpose is to be able to accurately measure the axle load without flattening the top surface of the measuring girder and the road surface in front and behind it, and to measure the axle load based on this axle load. An object of the present invention is to provide a vehicle weight measuring method that can measure the total weight of a vehicle with high precision.
更に、本発明の第2の目的は、車両の軸重を測定すると
共に一車両の軸重を自動的に総計して車両総重量を測定
し得る車両重量測定方法を提供することにある。Furthermore, a second object of the present invention is to provide a vehicle weight measuring method that can measure the axle load of a vehicle and automatically total the axle loads of one vehicle to determine the total vehicle weight.
更にまた、本発明の第3の目的は、被測定車両の車種判
別が可能な車両重量測定方法を提供することにある。Furthermore, a third object of the present invention is to provide a vehicle weight measuring method that allows the type of vehicle to be measured to be determined.

Find F and W B in step 12. The fluctuation period of this head envelope is based on the body vibration of the vehicle being measured. Therefore, when detecting axle load, good measurement results can be obtained by averaging the output over at least half of the fluctuation period. . The axle load value obtained in this way can be obtained by visually adding the number of axles for one vehicle, or by controlling a signal indicating that the vehicle is a vehicle by a photocell or a signal according to the vehicle identification procedure described below. - The total weight of the vehicle is determined (step 13).

A timing diagram is shown below. Next, with reference to FIG. 6 and FIG. 3, a method for determining whether or not the obtained axle load outputs are from the same vehicle will be explained. The signals from the detectors 5A to 5L input to the control circuit 9 are digitally processed and made into waveforms that only indicate the presence or absence of output as shown in the timing chart in FIG. 1
5, an output A' 15 is generated in section A, and the rear shaft 16
The output A]6 is generated. Similarly, the following vehicle 17
The front shaft 18 generates an output A18, and the rear shaft 19 generates an output A19. The same applies to other sections BL. From such output pulses, the axle load can be determined by knowing the timing difference t between the output pulses of the front axle or the rear axle passing through adjacent sections. That is, the axle load V can be determined as (2)=section distance, /1 (step 20). Output pulses that occur in different sections at the same timing represent the next axis. Compare the passing timing difference between these adjacent sections, for example, t2 and 11. Step 21) If the two are equal (however, if t2 and 11 are equal), then (including cases within the allowable range) −
It is determined that it is a vehicle (step 22). In the case of the example shown in FIG. 6, the output pulse A15. E1
5 is generated, and the timing difference with the pulse B16°F15 generated in the next section is t2 and t, respectively.
It becomes l. In this case, since t2 and tl are equal, it can be seen that the front and rear axles of the same vehicle generate pulses in sections E and A, and therefore in sections A to E.

. Since the timing differences t3 and t4 are not the same, it can be seen that the two axles of the same vehicle are not the same (step 22), but the inter-axle distances L D and T are measured (step 23). This L IJ
J indicates the inter-axle distance between the rear axle of the preceding vehicle and the front axle of the following vehicle. These inter-axle distances Ln, r are not added to the previously determined inter-axle distance LBF, but the total inter-axle distance is calculated (step 25). If t3 and t4 are equal, LBJ
is added to the LBF to determine the total center distance. This distance between the axles is also constantly scanned and measured at the same time as the axle load and U-sama move to adjacent sections sequentially, and when the distance between each axle is compared in step 24, from this change (
Step 22), - The vehicle can be identified (Step 22).

The type of vehicle, so-called vehicle type, is determined based on the total weight and total distance between the axles.

なってもよい。Although the procedure shown in Fig. 3 is as described above, it is not necessary to measure the distance between the axles in order to determine whether the vehicles are the same. It is sufficient to detect a change. In addition, to identify identical vehicles,
Steps 23 and 24 may be used to change only the distance between the axes.

This makes it possible to monitor and control overloaded vehicles, and to save labor and make toll road toll collection operations unmanned.

できる。As detailed above, according to the present invention, the axle load can be measured accurately without eliminating the vibration of the running vehicle by intentionally finishing the top surface of the measuring girder and the road surface in front and behind it to be flat. The total weight of the vehicle to be measured can be measured with high accuracy.

Therefore, according to the present invention, it is possible to accurately and efficiently control and monitor overloaded and speeding vehicles.

Since it is possible to determine the type of vehicle being measured based on the number of axles and the total number of axles, it becomes easier and more reliable to control vehicles that violate the loaded weight, and it also greatly simplifies ticketing and toll collection operations on toll roads. It has the advantage of being unmanned.

量測定方法。(3) In a method of measuring the weight of a moving vehicle by measuring the axle load of the vehicle, a bridge-like girder having a length greater than or equal to the longest axle distance of the vehicle has equally spaced sections less than or equal to the shortest axle distance. A detector for detecting shear force is provided in the vehicle, and when the vehicle runs on the girder, the axle load waveforms obtained from each of the detectors are sequentially superimposed, and the head of the axle load waveform based on the body vibration of the vehicle is The axle load of one axis is calculated by averaging the output over at least half the period of fluctuation of the part envelope, and the distance between the axles is measured from the interval distance where the output of the detector is simultaneously output. A vehicle weight measurement characterized in that it is determined from the change in the distance between the axles whether the axles are of the same vehicle or not, and the axle load obtained by the calculation is calculated to measure the weight of one moving vehicle. Method.
